TO ALL WHOM IT MAYICONCERN:

Be itknown that I, W. WALLICIQof Philadelphia, Pennsylvania, have invented an improved Machine for Feeding Nail-Plates;` and I'do hereby declare the following to be a full, clear, and exact description of the Asame, reference being had to the accompanying drawing, andto the letters of reference marked thereon.

My invention consists of certain mechanism fully described hereafter, by which nail-plates placed in a suitahlereceptacle are automatically withdrawn from the same and f ed to a nail machine, thus dispensing lwith the services of an attendant.

In ordcrgto enable-others skilled in the "art to make and use my invention, I will now proceed to describer its construction and operation, reference being had to the accompanying drawing, which forms a part of this specification, and in whichl Figure 1 is a vertical section of my improved machine for feeding nail-plates;

-Figure 2 is a transverse sectional view of the same. i Figure 3, a plan view. Figuref, thc same, with the working parts in a different position. Figure 5 is a sectionalview on the line 12, iig. 2. Figre 6 is a sectional view on the line 34,fig. 4. Figures 7 and 8 are detached sectional views of parts of the machine; and Figures 9 and 10, detached views drawn to an enlarged scale. vSimilar letters refer `to similar parts throughout the several views- To'the bed-plate A' of the machine are secured the opposite side-frames B and B', connect-ed by cross.

pieces l a', and the main driving-shaft C turns in suitable bearings in the opposite Side-frames, and in a standard, a, secured to the bed-plate. A sleeve, D, provided with a cog-wheel, b, is arranged to slide 'upon the square portion, c, cf the shaft C, for a purposedescribed hereafter, (see iig. 2.) Between the side-frame A and the standard a", and secured to the shaft C, .is a cog-wheel, d, and an eccentric, e, the latter operating a pawl, e', beneath which,V and resting upon the ,bed-plate and frame A of the machine, is a bar, f, having lan inclined lower edge, f', for a purpose described hereafter, (see figs. 5 and 8.) The harfis connected to an arm, g, one end of which is pi'votedto the cross-piece a of themachine, the other end being forked and entering a groove, g', formed in the sleeve'D of the driving-shaft. The pawl e is adapted tothe teeth of a ratchet-wheel, e, upon one end of a shaft, E, which turns in the opposite side-frames, and which is provided with two cog-.wheels, It and h', (see figs. 3 and 5.) i The wheel z gears into the teeth of a rack, z', secured to the under side of a bedplate F, which is arranged to slide in guides jj formed on the opposite side-frames A and A. A large cogwheel, G, gearing into the wheeloZ of the driving-shaft, is secured to a short spindle, lc, which turns in hearings in the standard a. and in a standard, c, secured to the side-frame A. A rocking-plate, H, is arranged tov vibrate in the bracketsk ik', and is provided with an arm, Z, which enters a cam-groove, l', formed on the inner face of the cog-wheel Gr,` (iig. 5.) Extending along one edge of the plate H is a rounded projection, m, tapered at one end, as shown in figs. 3 and 4, and this portion of the plate enters arecess, m', formed in a segmental pulley, I, which is secured to a spindle, n, turning in bearingsp and p on the bed-plate F. Two straps or flat chains, q and q', are secured to the segmental pulley I, and connect the latter to a rock-spindle, J, one. end of which turns in a rock-shaft, K, hung to the hearings p and r (figs. 3 and 4.) A projection, s, of the shaft K, bears against the face s of the spindle J, which is'partly inclined, as will bc seen on reference to figs. 9 and 10, and at the opposite side of theshaft K are two rounded projections or lugs, t t, and apin, t', passes through the spindle J, thc. object of which dcviccswill be rendered apparent hereafter.' The spindle J passes through a vertical slot, u, formed in a box on the hed-plate F, (fig. 7,) and is at this joint cranked, the cranked` portion, v, turning inA onc end of an arm, vl, thc other end of the Said arm being hung to a stationary pin, '02,allfor a purd pose described hereafter. The nippers L are hung to a pin, w, at the end of the spindle J, and the arms :v :l: of the said nippcrs are so connected by a spring, w", that the jaws x have a constant' tendency to remain closed. A. slot is cut in the spindle J for the reception of a plato, P, which is hung to a pin, y, and is ofthe peculiar shape shown in ig.l1. Project-ions, 22, which are formed upon each vside o f the plate P, enter corresponding recesses in the a'rms :v v of the nippers when Athe jaws of the latterare closed, as shown in iig. 4, and recesses 3 3"are also formed in thc said platefor a purpose described hereafter. A lever,Q, is hung to'a pin, 4, beneath the plate P, audits lower arm s forked, as shown in tig. 1, and embraces a pin,5, at one end of a plate, R, which is arranged to vibrate upon a pin, G. The plate R, at its lower end, is provid-ed with two lugs, 7 and 7', and the side-frame A of the maehinehas a projection, 8, fora purpose described hereafter, (iig. l.) Two brackets, S S, are lsecured to the side-frame A of the machine, in peach of which, as shown in figs. 3 and 4, is formed a recess, 9, and a portion of a frame, T, which slides in guides formed on the brackets, is cut away, as shown in fig. 6, seas to present an abrupt shoulder, 10, and an opening, 11, is formed in each of the brackets for a purpose describedhereafter. The forked arm of a bell-crank lever, U, which is hung toone of the brackets S, passes around a pin, 12, of the bed-plate F, and the short arm 13 of the said lever projects' over the bed-plate F, en which is a block, V, having two lugs, 14 vand 15, which will be referred to hereafter.

. Operation.

The plates z, shown in red lines, figs. 1 and 3, and from which nails are to be mace, are -laid one upon another in the recesses 99 of the brackets S, which, together, form a box for their reception, and on reference to fig. 6 it will be seen that the bottom plate s rests. upon the frame T, and is in contact with the shoulder 10 of the same. Let it be supposed that the working parts of the machine are in the position shown in iig. 4, and let the red line Y represent the shears of-a nail machine. Power isiapplied to the driving-shaft C, and is transmitted by the'cog-wheels I) and it to the shaft E and cog-wheel z., andas this latter wheel gears into therack z' the sliding platform F is moved in the direction of the arrow 1, tig. 4:. The bed-plate F continues moving, and

'the narrow lug 15 of the block V passes the arm 13 of the bell-crank lever U, which is struck by the` lug 14 and'moved so as to push out the frame T and bottom nail-plate z to the position shown in tig. 3, or until the centre of the plate z coincides with that of the spindle J, the segmental pulley I passing from contact with the projection m of the plate H, so as not to be operated by the latter. Owing to the arrangement 'of the arm v1,

'the spindle J, and pins v v2, the spindle, whenresting upon the lower end ofthe slot u, will be so`turned that the nippers will be in a vertical position, and the plate P will bein the proper position to bev brought in contact with its operating devices. At the saine time the lug 7, iig; 1, of the plate R, strikes the projectionS of the side-frame A, the plate lt is moved on its pin G, and through the medium of the lever Q, the end of which enters one of thc recesses 3 of the plate l?, the latter is turned from its position, iig. 4, to that shownin'iig. 1, thereby forcing open the jaws rc of the nippers L. Then, by means ofany ordinary mechanism connected with.l the nail machine, the sleeve D of the shaft C is moved to the position shown in figs. 2 and 3, thereby throwing the cogwhecls b and t outof gear, and the barf, through the medium of the arm g, is moved from the position shown Vin dotted lines, fig. to that shown in full lines, thereby causing the pawl e', g. 5, to drop to the teeth tof the ratchet-wheel e ou the shaft E. As the shaft C continuesto revolve the ratchetwheelc is turned slowly by the pawl e', and through the medium of the cog-wheel L the bed-plate Fiis moved slowlylin the direction of the arrows 2, figs. 1 and 3, until the jaws of the nippers L reach `the end of the plate s. Then the ylug 7 of the plate R strikes the projection 8 ofthe side-frame and turns the plate P, as above described, when, by the action of the spring w', the jaws rv of the nippers are suddenly closed and the end of the plate z is held securely between them. At thc same time the lug 15 of the block V strikes the arm 13 of thebell-crank lever U, which is moved until the frame T is drawn back toits original position, leaving the plate e between the jaws of the nippers.` By means of the camgroove l ofthe cog-wheel G, tig. 5, a rocking motion is imparted to the plate .-H, and as the bed-plate F advances towards' the same the tapered end of the projection m of the plate enters the recess m of thc segmental pulley I, to which the rocking motion of `the plate is imparted. This motionof the pulley is transferred to the rock-spindle J by means of the straps q and q', vthe strap q turning the spindle when the segment is moved in one direction, and the strap'q turning the spindle in the opposite direction when the motion of the segment is reversed. 4

' 4It 'should beunderstood that the machine is so arranged that this rocking motion of the spindle J never exceeds one-half of a revolution in either direction, thus insuring a uniform turning of the nail-platc z 'as it is fed up, so that opposite tlat sides of the same shall be alternately presentedito the action of the shears of the nail machine; As the plate rests upon a table while being cut, it must be raised in order to be turned, and at the same time be drawn back a short distance to avoid striking the shears. The raising-of the spindle and plate is effected by means of the cranked portion o of the spindle and the arm v", for the spindle J (iig. 7) is confined in the vertical slot u, and the cranked portion turns on the pin e; hence it must necessarily rise and fall when turned, its bearing in the rock-sliaft K permitting such motion. When the spindle J is turned in the direction of its arrow, g. 9, the pin t/strikcs the rounded projections tt of the rock-shaft K, and as the pin is turned on them the spindle is-drawn back to the position shown in iig'. 10. When the motion of the spindle is reversed its inclined face s com-es in contact with and turns upon the projection s of the shaft K, by means of which the spindle is pushed forward to its original position, iig. 9. The forward motion of the bed-plate F is continued until all of the plate z', except the small portion held in the nippers, has been fed to the nail machine, when the cog-wheel b is again thrown into gear with the wheel t, and the bed-plate F is moved rapidly back.l The reversing of the motion, as before described, operates `the arm g, and the bar f is drawn back and raised by reason of its inclined edge f', as shown by dotted lines, iig.v 8, thus withdrawing the pawl e from the teeth of the ratchet-wheel e. The backward motion of the platform is continued until another plate is pushed forward and the jaws of the nippers opened, when the motion is again reversed, vthe plate grasped, and the operation goes on as before. l
